Friday at the track I heard a girl asking why some of the cars have holes drilled into the bumpers. So a guy, I guess she was with, told her it was for wind resistance for interstate driving/racing and that only the fast cars have them. So she sees a car pull a faster time them the "real fast" cars with holes in the bumper. She asks, "Why doesn't that that car have holes in the bumper"? "It was a lot faster then the one with holes".

So by this time Im thinking to myself that these people cant be serious and are just Nick and Jessice Simpson in disguise. Because they sound too stupid to be taken serious.

Could someone humor me as to why people put holes in their bumper..........on purpous?
